Abstract
In the case of a spinning or twisting spindle, it is provided that the spindle shaft is radially fixedly disposed in the spindle bearing housing, and that centering devices and vibration damping devices are integrated into a holding arrangement for the spindle bearing housing.
Claims15
A spinning or twisting spindle arrangement comprising:
- a spindle shaft,
- a spindle bearing housing accommodating a bearing for the spindle shaft, said spindle shaft being radially fixed in the spindle bearing housing,
- a spindle rail including upper and lower axially spaced flanges,
- and holding devices at each of said flanges for holding the spindle bearing housing, each of the holding devices including rubber-elastic elements disposed between the flanges and the spindle bearing housing so as to prevent a metallic connection between the spindle bearing housing and the flanges while permitting radially swinging movements of the spindle bearing housing,
- wherein the holding devices at at least one of the upper and lower flanges includes radial aligning devices for accommodating selective adjustment of radial alignment of the spindle housing relative to the respective flange.
2 more elements
An arrangement according to claim 11, wherein the holding devices at the upper flange include an annular damping element arranged between a flange of the spindle bearing housing and the spindle rail.
A spinning or twisting spindle arrangement comprising:
- a spindle shaft,
- a spindle bearing housing accommodating a bearing for the spindle shaft, said spindle shaft being radially fixed in the spindle bearing housing,
- a spindle rail including upper and lower axially spaced flanges,
- and holding devices at each of said flanges for holding the spindle bearing housing, each of the holding devices including rubber-elastic elements disposed between the flanges and the spindle bearing housing so as to prevent a metallic connection between the spindle bearing housing and the flanges while permitting radially swinging movements of the spindle bearing housing,
- wherein the holding devices at the lower flange include radial aligning devices for accommodating selective adjustment of radial alignment of the spindle housing relative to the respective flange, and
- wherein the spindle bearing housing is provided with an axial extension in the downward direction beyond the spindle shaft, and wherein the holding devices at the lower flange are applied to the axial extension.
